(WILLIAMSTON, MICH.)(AP) -- An 8-foot wall collapsed in a Michigan high school locker room, killing a 14-year-old student who had jumped and grabbed for the top to do a pull-up, police said Thursday.

Williamston High School freshman Gabriel Corbett was buried under cement blocks Wednesday and later pronounced dead at a hospital, Police Chief Bob Young said. It was not known why the interior wall came down. He was in full cardiac arrest before being rushed to the hospital, Young says.

There was "absolutely no" horseplay by the victim or another student who was in the locker room.
"The young man was trying to do pull-ups on the wall. He grabbed the top of the wall and that's when it came down," the police chief said.

District finance chief Steve Cook said there had been no reports of structural problems in the locker room, which was built in 1990.
